  1. fe_10.elvlc (energy levels)
  2. contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.

     
    
    Theoretical energies:

  3. fe_10.wgfa (radiative data)
  4. contains wavelengths, gf and A values of the transitions. The wavelengths are based on the experimental energy levels and should be the best available. Wavelengths calculated from the theoretical energies are of an indeterminate accuracy and their values are presented as negative values of the calculated wavelength.

    %filename: fe_10.psplups
    %rates: Bhatia A.K., Doschek, G.A., ADNDT 60, 97, 1995
    %rates: Bely O., Faucher P., A&A 6, 88, 1970 (for 1-2 transition)
    %energies: Observed energies from .elvlc file, except for level 10 for which 
        the theoretical energy from the .elvlc file is used.
    %comment: For all transitions except 1 - 2, the rates were only tabulated at 
        one temperature. I have fit this data with a straight line that is 
        forced to be zero at a scaled temperature of 0 to emulate the 
        behaviour of proton rates.
    %comment: Fitted using single_temp.pro with scalx=0.90
